Nitrourea (NU), also known as N-nitrourea is an organic chemical compound, a powerful explosive material. It has the formula H2NC(O)NH(NO2).
Nitrourea hydrolyzes to form nitroamide and isocyanic acid.
Nitrourea burns when ignited and may explode under the right circumstances.
Nitrourea is a hygroscopic white solid, soluble in water.
Nitrourea is mildly sensitive to heat and shock, may explode under exposure to intense heat or fire.
Nitrourea is not sold by chemical suppliers and has to be made in situ.
- Pyrotechnic demonstrations
Nitrourea is a powerful explosive material and should be handled with care.
Should not be stored for long periods of time, as it's prone to hydrolysis.
Should be diluted and hydrolyzed.
